DUPLICATING' MEMORANDUM-BOOK OR COPYING-BOOK.

SPECIFICATION formingpart of Letters Patent No. 537,232, dated-April 9,1895.

' Application filed January 13,1894. 111i... 466,826. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM H. RODDEN, commercial traveler, of the city of Toronto, in the county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in Duplicating Memorandum- Books or Copying-Books; and I hereby declare the following to be a full, clear, and'exact deing across, the, ledge formed by the edges of the stubs over which. it must extend. This ledge increases in height as the copy leaves aretaken from their stubs,thus preventingthe 2'5 transfer sheet from lying flat and close to the,

leaf which is to receive thecopy as required.

Second. It has also been found essential especially in counter check books where sales are made on credit account and also in commercial travelers order books, to retain the copies in the book and yet to have the attached transfer sheet kept adjacent to the next leaf to be copied on. This has been found impracticable hitherto owing to the retained copies intervening between the transfer sheet and the leaf to be copied on.

Third. The permanent attachment of the transfer sheet to the book is often found to be a disadvantage. Sometimes this sheet outlasts the book and is therefore lost to use. Sometimes the book outlasts the sheet, and there being no convenient provision for attachin g a new sheet, it is troublesome to do so. A poor remedy for this has been attempted by putting two or more transfer sheets in different positions in the same book, and the second transfer sheetis frequently not required.

Fourth. The object of my invention is to construct a copying book of the desired form 50 with the transfer sheet so attached and arranged that the aforementioned impediments To secure the greatest convenience in'the'v First. It necessitates the transfer sheet ly-' andobjecti'ons .will be obviated; and the invention consists essentially of the improvements as described hereinafter and as set forth in the claims.

In the drawings, Figure l is a perspective viewofa copying book showing the stub, the original and the copy leaves, the frame orlink pivoted at the bound end of the book, and the transfer sheet attached to the pivot yoke or link. Fig. 2 is a perspective view'of theyoke or pivot link and the temporary binder.

Like numerals and letters of reference refer to likeparts throughout the specification and drawings.

The copying book consists of a series of stubs 1, duplicates 2, and sales slips 3. The stubs 1 are bound together in the usual manner for securing together the several leaves comprising the book. As shown in the drawings the link or yoke 6 is pivoted to a tempora'ry binder 8 secured to the head of the "book. -The link or yoke 6 comprises three sides of a rectangle and part ofthe fourth, numberedrespectively 6, 0 6", and 6 The open space between the sides of this yoke or link is of a sufficient size "to permit of the leavesconstituting the book being drawn therethroug'h. The ends 6 of the sides of the frame 6, respectively, 6 and 6, are bent at right angles in the said frame and are secured preferably to the temporary binder 8 in such a manner that they serve as axes about which the side 6" rotates. Secured to the side 6 of the yoke or link 6 is the transfer sheet 7, which is also adapted to swing during the rotation or semi-rotation of the yoke or link 6. The transfer sheet 7 is secured to the side 6 of the link or yoke 6 by means of a clamp 9 which comprises a folded piece of metal having two openings 10, one arranged at either end of the clamp, through which pass the sides respectively 6 and 6. The side enters the fold of the clamp 9, and it is by means of the side 6 entering the fold ofthe clamp 9 that the transfer sheetis secured in place. This is accomplished as follows: The clamp 9 is slid, on the sides 6 and 6until the side 6 is entirely clear of the clamp. One end of the transfer sheet is then placed between the side 6 and the clamp 9, and the clamp is then slid back into place, binding the transfer sheet in its fold between itself and the side 6. The clamp 9 is held against the side 6. by means of two springs 11, one wound on each of the sides 6 and 6 respectively, which press the clamp 9 against the said side 6 and hold it with sufficient pressure against the said side 6 to firmly retain the transfer sheet in place. The ends 6 of the sides 6" and 6 respectively of the frame 6 are inserted in a socket or keeper 12 formed in the temporary binder 8.

I do not confine myself to any particular form of link or yoke, as I may, ifI find it convenient, secure the transfer sheet to any convenient form of link or yoke, and secure the link or yoke in any convenient manner to the book, so that it will swing the transfer sheet clear of the stubs in a mannersimilar to that of the frame 6. i

If required to retain the copy instead of removing it from the book, it can be permitted to remain attached, and can be passed backward through the frame 6, so that the transfer sheet 7 will be in place to lie upon the next unused leaf readyto be used for its purpose.

side connected to the said opposite sides at right angles thereto, a substantially U shaped sliding clamp working on the said opposite sides and arranged to bear against the said third side to removably bind the transfer sheet between itself and the said third side, springs coiled on each of the said opposite sides and arranged to press and hold the clamp against the said third side the ends of the said opposite sides bent inwardly at substantially right angles to themselves and adapted to connect the said link to the book, substantially as specified.

2. In a copying book, the combination with the originals and duplicates, of a swinging link revolubly connected thereto consisting of a quadrilateral frame, springs coiled on opposite sides of the frame, and a U -shaped sliding clamp, working on two opposite sides of the frame and arranged to bear against the front side of the frame, substantially as shown and described.

3. In a copying book the combination with the originals and duplicates of a swinging link revolubly connected thereto consisting of a quadrilateral frame, a U-shaped sliding clamp working on two opposite sides of the frame, and arranged to bear against thefront side of the frame, springs coiled on each of the opposite sides and arranged to press the clamp against the front side of the frame, substantially as specified.
